This year marks the 50th anniversary of Star Trek, and from the first episode in 1966, the Starfleet uniforms worn by the crew of the U.S.S. Enterprise (and eventually elsewhere) have remained one of the most enduring and iconic aspects of the franchise. Aside from being deliberately utilitarian and futuristic, from the beginning, the uniforms have also been used to communicate a character’s rank and station, although depending on what period in the future you are trying to emulate, the language changes.
